[Allison 8 crossovers]

Thanks I will try that They are CD8  I am also thinking that if its possible the ferrofluid dried up and may cause the problem

Hello again to all   I have a set of Allison 8 speakers that may need a cap  job   Seems at certain bursts/spikes at mid volume the speaker looses volume and crackles  There about 35 years old now

 

Does anyone have a schematic of what caps I need to replace?

Maybe it was this? Wire touching the frame and shorting out?

Hi thanks for your input  My concern is that  there are no problems with the CD7 in the back channel    I guess the B channel may get less wattage then the A channel so they dont clip?

I just played two CD s for about an hour at moderate to loud volume and no problems with any speaker.  Thats why I lean toward s the CD7  Maybe the ferrofuid in the tweeters are dried up or the cap is dried up and when under a high wattage load it creates the clipping??

Hello new member to this forum.  I would like to ask for some help.  I have a NAD 7140 receiver and two pairs of Allison 7 speakers.  One set is the CD-7 series used for the back channel (B) All owned since new.  I had no problems with these with the receiver but came upon a problem when i switched the CD7 to be the main speakers and the regular Allison 7 to the back speakers (B)  While playing a cd on my  Parasound cd player on moderate volume  the CD7  speakers started to distort and lose volume on both speakers  the back speakers were fine.  I checked all wiring and all ok.  I turned off the receiver and tried playing the cd and the receiver did the same thing after a a few minutes    Strange thing is I then changed the CD7 to the B side and the regular Allison & to the front (A)  Problem went away.   With this setup  I can play all day at high volume without any problems

Could it be the caps in the CD7 creating the problem?   The crossover in the CD7 is different. It has two coils and a small blue resister?       Any recommendations on replacement caps for both crossovers?
